Title: Rotary damper
Inventor: YAMAGUCHI KEIJI
IPC: E05F5/00
Filed: 1993-02-17
Abstract: PURPOSE:To facilitate manufacturing and assembling and raise damping force even if the diameter is enlarged and the axial length is elongated by connecting two caps at both ends by a stirrer stirring granules in a cylinder case. CONSTITUTION:A stirrer 6 is an elliptic cylinder 11. Caps 2 and 3 are provided with oval projecting shafts 12 and 13 trushing into respective ends of the elliptic cylinder 11 on two opposed surfaces, fitting these projecting shafts 12, 13 in respective ends of the cylinder 11 and thereby they are connected to each other. This elliptic cylinder 11 is made of stainless steel, by way of example, and the major axis is little shorter than an inner diameter of a cylinder case 1. When this cylinder case 1 is fixed, and torque is transmitted to either of these caps 2, 3, the elliptic cylinder 11 and the cap on one side try to rotate as one body, so at this time, since the elliptic cylinder 11 has to stir granules 4 compactly filled up in the case 1, the transferred torque is thus damped. Accordingly, a stirrer 6 for damping this transferred torque merely stirs the granules 4, whereby a clearance between this stirrer 6 and the cylinder case 1 is allowed to be large enough.

IPC: G01B7/00
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a high-accuracy detection signal even in an atmosphere where temperature variation is large by setting output voltage characteristics of a couple of magneto-resistance elements which constitute a magnetic detecting element into opposite states according to the variation in temperature and compensating them mutually. CONSTITUTION:A moving body 11 constituted including a magnet is set as a body to be detected. Then the intensity of a magnetic field which operates on 1st and 2nd magneto-resistance elements(MR) 12 and 13 varies according to the displacement caused by the movement of the moving body 11 and their resistance values vary respectively corresponding to it. Further, the resistance variation rates of the MRs 12 and 13 have a negative temperature coefficient -alpha. Then the output voltage from an output terminal 14 varies with temperature unless temperature correction is performed, so 1st and 2nd constant voltage circuits 15 and 16 are given temperature coefficients alpha/2 and -alpha/2 respectively. Thus, variation in the deviation quantity of the output voltage from the terminal 14 with the variation quantity of the moving body 11 is eliminated. Further, the temperature coefficients of the circuits 15 and 16 are set opposite to each other and their neutral point potential does not vary and becomes constant.

IPC: G01R31/302
Filed: 1983-03-28
Abstract: PURPOSE:To indicate the levels of the electric potentials of a wiring and the image of the distribution of insulating matters by detecting thermal waves excited on the surface of an LSI due to the irradiation of an electron beam and combining the wiring, obtained from a thermal wave signal, with the image of the distribution of the insulating matters and the image of the distribution of electric potentials produced by a secondary electron signal. CONSTITUTION:A sample LSI 1 is periodically driven by an LSI-driving circuit 2 according to data sent from a memory 21. An electron beam discharged from an electron gun 17 is turned into pulses synchronously with the LSI1 by means of a stroboscopic device, then irradiated upon the LSI1. Secondary electrons discharged from the LSI1 are detected by a secondary-electron detector 13, and a secondary electron signal is turned into a binary one by means of the binary circuit of a picture-treating circuit 12. On the other hand, thermal waves excited on the surface of the LSI1 are transferred to an ultrasonic detector 9 in which they are converted into a voltage signal. The thus obtained signal is sent through a sampling circuit 11 to the circuit 12 in which it is turned into a binary one. The circuit 12 treat both of the above binary signals to obtain a ternary image which corresponds to wiring patterns of a low and a high electric potential and insulating matters, thereby enabling three-colored indication for example to be realized on a displayer 14.

Filed: 1992-03-09
Abstract: PURPOSE:To obtain a satisfactory tansfer image on the surface of a recording sheet without the sheet being soiled by applying a sheet electrifying bias before the front end of the recording sheet enters a sheet electrifying device. CONSTITUTION:A sheet electrifying brush 34 is pressed to a transfer belt 31. Before a sheet of recording paper P enters a sheet electrifying part, a sheet electrifying switch SW (PC) is turned on with a little allowance of time (time T) left. During the time T, the sheet electrifying brush 34 slides against the transfer belt 31 with a sheet electrifying bias applied thereto, and toner sticking to the sheet electrifying brush 34 moves onto the transfer belt 31 to stick thereto and is carried away. Also, by repeating the on/off operation a number of times by the time the front end of the sheet enters the sheet electrifying part after the sheet electrifying brush 34 abuts on the transfer belt 31, toner is shifted to the transfer belt 31 from the sheet electrifying brush 34, which is accompanied by each on-operation, and more effect can be expected. When a fresh sheet of recording paper P enters, the surface of the sheet is therefore little soiled.

Title: System for setting intra-program constant value
Inventor: NAKAGAMI HIRONORI
IPC: G06F9/06
Filed: 1987-03-06
Abstract: PURPOSE:To easily change the constant value by using a constant memory means which stores the value of a constant used in a program, a constant induction means which induces the value of the constant stored in said constant memory means into the program in an initialization process, and a constant changing means which changes the value of the constant stored in the constant memory means. CONSTITUTION:When an automatic operation control program 1 is started, a constant induction means 5 sets the value of a constant i.e., a specific program start time point stored in a constant memory means 4 at a start time point memory means 3 via an initialization process. Then a constant time point start control part 2 works to start a specific program at a start time point with reference to the means 3. If the specific program start time point is changed owing to the change of the system operating conditions, both a change information input means 6 and a constant change means 7 are used to change the value of the constant stored in the memory 4. Thus the value of the constant changed by the means 5 is induced to the means 3 on and after the following date. Thus the constant value can be changed without correcting a program itself.
